The babies utilized one amniotic sac but separate umbilical cord, which bothered doctors because it could become tangled and kill them both
The identical twins defiled all odds by engaging in a life-saving hug.

Nursery nurse Vicky Plowright, 30, was informed at the tenth-week scan that the twins were monoamniotic - meaning they used only one amniotic sac.
The doctors warned that this meant their umbilical cords could become entwined cutting off their oxygen supply, hence killing them.
A fortnight later, another scan was conducted. The sonographer informed Vicky, of Godalming, Surrey, her babies pulled off a life-saving embrace posture.
Miraculously, their embrace halted their cords from becoming tied up.
“To our astonishment, at the 12-week scan, we saw that they were cuddling each other and holding hands,” Vicky recalled.
“They kept each other alive by staying closely knit. So their umbilical cords didn’t tangle.”

Vicky, whose fiancé, Chris Cremer, 32, is also a nursery nurse, said her sister, Georgina accompanied when she received news that the twins were monoamniotic, or Mo-Mo (Monoamniotic-Monochorionic), twins.
She explained: "This is a very uncommon situation affecting one in 35,000 and one in 60,000 twins in the UK, and means they shared one amniotic sac, instead of having one each.
“I was sad, as doctors also told it meant the babies were at a high risk - they had about 50 percent chance of surviving and not surviving because of the pregnancy because of the proximity.
"They had two umbilical cords, to supply nutrient, which could become tied up leading to strangulation. The thought of it was scary to imagine."
Vicky had gone to the tenth-week scan with Georgina, expecting it to the usual routine of getting updates on the baby’s well-being and relaying it to Chris.
Rather, she said: “I was stupefied as I was just telling my sister as long as they are not two, since we already have a daughter, Jocelyn, four, and I didn’t think we had the strength for two more.”
But the laughter came to an abrupt end when, moments later, the sonographer informed them the twins appeared worryingly close together.
Instantly, an internal scan was conducted showing no possibility of them being conjoined, but doctors were still worried about the babies.
“The scan showed our twins were sharing the same amniotic sac,” Vicky explained.
“They said it meant the babies were in danger and we needed to see a specialist.
“I went Crazy and rang Chris as I had no idea what this meant.
“Within an hour I was told we were expecting twins, but they could be in danger. It was heartbreaking thinking I could lose them in at any time.
But everything turned around in the twelfth-week scan, when a specialist sonographer, Informed Vicky and Chris that the twins had moved into a lifesaving embrace.
In a miraculous moment, the couple witnessed their boys joyfully hugging each other and holding hands.
“By staying still in that position, they’d stopped the cords from becoming so badly tangled that it killed them,” Vicky said. “It really was a miracle.”
Doctors arranged to see Vicky every week or two weeks for examination until the twins attained 32 weeks when they wanted to deliver them.
“For the next couple of months, our hearts were in our mouths,” said Vicky, who found out at 17 weeks we were expecting boys.
“I didn’t think I could get elated because I was so disturbed because I had this nagging thought that we were going to be told at every scan that our twins did not make it.
At 13 weeks one twin’s cord slightly wrapped around the other, making them lie even closer and stiller. Fortunately, it meant a major knot was less likely to take shape.
Then, at 32 weeks, Vicky was happy when she was told it was better she gives birth to her babies, as twin number two, Theo, had stopped growing because there was no more room for expansion.
So, on December 22, 2015, she was transported to a delivery suite at the Royal Surrey Hospital in Guilford for a cesarean, with Chris by her side.
With Ed Sheeran’s 'Photographs' playing in the background, Reuben came to the world at 11.22am weighing 3lb 14oz, followed by his identical twin brother, Theo, just one minute later, weighing 3lb 7oz.
“Both of them came out crying. Gladly, they were alive,” Vicky recalled.
“Chris was crying next to me, as well. We were just so excited that they fought through and emerged victoriously.”
Vicky was discharged on Christmas Day, enjoying a festive lunch at her parents Gerry and Rita Plowright’s house, then returning to the hospital to see the boys that evening.
The twins were observed in the neonatal unit for another five weeks, before being discharged at the end of January.
Now, they are 22 months old, they could not be closer.
“Before they came to the world, they knew each other and developed together in such a tiny space.From then, I knew they would have a telepathic bond for the rest of their lives.
“Reuben is the performer and Theo is the ‘thinker’, but they always have an eye on where the other is.”
Bliss, a charity organization for babies born premature and sick, supported Vicky by providing her with access to information and Services she needed.
